5'4" roughly, 110 pounds, and I ride a 15.1hh Anglo Arab - he is pretty chunky though. I like them anywhere from a solid (cob type) 13hh upwards and LOVE them around 16hh. I ride jumpers and playing around with the idea of getting into eventing.
The little miss is about 13.2 at 11 months and hopefully will be 15hh but I think it'll be pushing it. But if she has much of her sire's genetics she will be solid, so I won't have a problem.
I look good on anything from a 13.3 welsh cob to a 16.1 solid built TB and I will admit that TB was about the tallest I've ridden. I have REALLY long legs so it can be hard to find a horse that really takes up as much of my leg as I would like. Monty does at a push, I would love another hand or so of height on him, but he's not REALLY chunky, just sort of medium... I am used to relatively slender horses so he is chunky in my eyes.
